Appendix C: Wiring Requirements
Connecting external system accessories to the AUDIO•COMMAND•CENTER•25/50 Series main
circuits must be carefully considered to ensure proper operation. It is important to use the correct
type of wire, wire gauge and wire run length per each circuit. Refer to the following table to spec-
ify wire requirements and limitations.

NOTE: If an SLC loop is to be run in conduit with AUDIO•COMMAND•CENTER•25/50 Series
Notification Appliance Circuits, the risk of encountering problems can be greatly reduced by using
twisted, shielded cable on the SLC and NACs.
